Centrum mechanical strength evaluation method and device, computer equipment and storage medium

Abstract

The embodiment of the invention discloses a centrum mechanical strength evaluation method and device, computer equipment and a storage medium. The method comprises the following steps: acquiring CT image data of a vertebral body; extracting a single segment of the vertebral body from the CT image data of the vertebral body as a to-be-evaluated vertebral body to carry out three-dimensional construction so as to obtain a three-dimensional structure of the to-be-evaluated vertebral body; carrying out discrete processing on the three-dimensional structure of the to-be-evaluated vertebral body to obtain a plurality of discrete unit bodies; adding discrete unit bodies used for representing splints to the upper surface and the lower surface of the to-be-evaluated vertebral body; carrying out material attribute description on the discrete unit bodies to endow the discrete unit bodies with corresponding bone mineral density, Young modulus and Poisson's ratio; applying boundary conditions and constraint conditions to the discrete unit bodies used for representing the clamping plates, and establishing a stress and strain relation equation set of the to-be-evaluated vertebral body according to the material attributes of the discrete unit bodies; and based on the stress and strain relation equation set of the to-be-evaluated cone, evaluating the to-be-evaluated cone under a preset load to obtain the mechanical strength of the to-be-evaluated cone.

Description

technical field [0001] The invention relates to the field of medical data processing, in particular to a method, device, computer equipment and storage medium for evaluating the mechanical strength of a vertebral body. Background technique [0002] According to the National Health Report, osteoporosis has accounted for an important proportion of national medical expenditures, and osteoporosis will have a serious impact on patients and national medical expenditures. In the clinical field, the prediction of the risk of spinal osteoporotic fractures has become the primary link in the prevention of osteoporotic fractures. [0003] The existing technical scheme is based on clinical medical imaging technology, such as CT (Computed Tomography) image, through biomechanical finite element analysis, simulates the stress of the spine in the human body, and compares it with the statistical results of the spine stress of healthy people, evaluates The health of the vertebral body and the...
